Baeyer-Villiger reaction of ketones by using sodium percarbonate as oxidant in acetic anhydride was reported in this paper. Cyclic ketones were converted into corresponding lactones in about 80% yield. Aromatic ketones, however, did not give reasonable yield except those in which the aryl ring was activated. It was found that the reaction time can be greatly shortened by ultrasonic irradiation. The role of sodium percarbonate in Baeyer-Villiger reaction was also discussed.
